## Discrepancy

DURING TAKEOFF ROLL, THE PILOT OBSERVED THE ADAS TREND LIGHT BLINKING. THE PILOT ELECTED TO ABORT THE TAKEOFF AND CONTACT MAINTENANCE. MAINTENANCE RECEIVED NOTIFICATION FROM THIS ALERT OF AN ENGINE OVER-TORQUE. HOWEVER, DUE TO PREVIOUS MAINTENANCE ON THIS SYSTEM AND ENGINE INSTRUMENT READINGS DURING THE INCIDENT, IT WAS DETERMINED THAT THE ALERT WAS FALSE AND WAS CAUSED BY A FAULT IN THE ADAS SYSTEM. THE ADAS SYSTEM WAS THEN DEFERRED PER MEL, AND THE PILOT CONTINUED HIS SHCEDULED ROUTE WITH NO FURTHER INCIDENT.
